Abstract: A method for making glass material lens array, comprising: Step 1: providing a mold device, an upper mold, a lower mold a plate structure having plate body and through holes, and a plurality of lenses having lens body portions and annular portions; Step 2: placing the plurality of lenses on the lower mold cavities of the lower mold; Step 3: disposing the plate structure between the upper mold and the lower mold, to align the through holes with the lenses; Step 4: moving the plate structure downward, to have the lenses received within the through holes; Step 5: closing the upper mold and the lower mold, to make the upper mold pressing region abut and press the plate body; and Step 6: forcing and squeezing the plate body of the plate structure to deform, and generate a deformed region B flowing and covering a periphery of the annular portion.

Abstract: A molding device for lens array is disclosed and for pressing a plurality of lenses onto a plate structure, the plate structure comprising a plate body having a thickness T1 and a plurality of through holes disposed in the plate body. The molding device includes an upper mold and a lower mold. The upper mold has a plurality of upper mold pressing regions and a plurality of upper mold cavities, and the lower mold has a plurality of lower mold pressing regions and lower mold cavities. The plate structure is movably disposed between the upper mold and the lower mold, the plurality of pre-manufactured lenses are respectively disposed in the plurality of through holes of the plate structure for manufacturing.

Abstract: A mold apparatus of a lens array and a method for using the same are provided. The mold apparatus includes an upper pressing die, a lower pressing die and a plate structure. The upper pressing die includes a plurality of upper engaging portions. The lower pressing die includes a plurality of lower engaging portions. The plate structure includes a plurality of through holes. A glass article is installed at the through hole. The glass article includes a first sectional width W1. The through hole includes an upper opening and a lower opening. The upper opening corresponds to the upper pressing die. The lower opening corresponds to the lower pressing die. The upper opening includes a second sectional width W2. The lower opening includes a third sectional width W3. Wherein W1?W2 or W1?W3; the glass articles are extruded by the mold apparatus to manufacture the lens array.

Abstract: A thermal-chemical polishing device and method for polishing a diamond film of a workpiece, the device includes a horizontally displaced first rotatable high rpm shaft and a vertically displaced second rotatable high rpm shaft that are perpendicular. The first shaft is made of a material from transition metals or rare-earth elements which undergo a chemical reaction with the diamond film at high temperature. The circumferential surface of the first shaft has a predefined heating region. The second shaft moves axially towards the first shaft to allow the diamond film to make contact with the heating region of the first shaft. A heating unit is provided to heat up the heating region to create a chemical reaction for thermal-chemical polishing to perform while the diamond film is in contact with the heating region. The device of the present invention increases the rate of polishing and also decreases cost.
